firra riged within wnd spaced below the cover plate I ef' fra me 1 1 1 is a plate 21 which lieri'z ont-elly fills tl re speeefwltlflh the frame The apertures 15 are preferably slightly larger than the passage 10 so as to allow the lower end portion of shank 11 to pass down into the respective aperture 15 freely when the carriage 3 is projected with just the right velocity to come to rest with the shank 11 in line with the given aperture 15. However, the lower end of shank 11 is rounded or formed cam-shaped, as seen in Figure 1, and if the carriage is moving with sufficient velocity, the shank will ride past and over an aperture 15 and may ride over all of them. Thus the shank 11 will drop into one of the apertures 15 or will be sustained by an intermediate imperforate portion of plate 21, according to the point at which carriage 3 comes to rest, and the doll 12 will not be projected when this occurs.

Should the carriage 3 approach a position over one of the apertures 15 at just the required velocity to permit the lower end of the shank 11 to pass down through the aperture, the doll 12 will be first allowed to drop for substantially that portion of the length of shank 11 normally above the carriage 3, and will then be projected through a trajectory describing a graceful curve and cansing the doll to plunge into the water of tank 16 arranged at the forward end of frame 1. The incline of the passageway 10 and of apertures 15 insures the projection in such form as to cause the doll to turn and descend head foremost in imitation of a dive. It will be obvious, of course, that for use by small children or otherwise as a toy, it may be sufficient to provide the mere picture, or other imitation, of a pond on which the doll will light instead of providing the tank 15 with its supply of water. At amusement places, or under conditions where ,it is desired to attract special attention, the water will usually be provided.

The trip mechanism, which is actuated when the shank 11 drops through one of the apertures 15, is automatic, in so far as functioning is concerned, at the time of the projection of the doll, but is preferably of the re-set type for each separate operation, and

such mechanism includes a trip rod 17 fixed to and projecting horizontally from a cam 18 pivoted to a bracket 19 outstanding rearward from the front end of the frame 1. Rod 17 is of a length and location to lie across all of the apertures 15 and of a size transversely to fit within the recess 14 of the shank 11. The rear end of the rod is left free, so that pressure on the rod will cause the cam 18 to swing upon its pivot and cam downward the upper face of a block 20 carried by a lever 22. Lever 22 is pivoted intermediate its ends to an upstanding bracket 23 sustained by the lower portion of frame 1. The forward end portion of lever 22 is preferably guided by a pair of brackets 24 fixed to and upstanding from the same plate of frame 1 as that carrying the bracket 23. The lever 22 swings between the brackets 24 and is prevented from having any torsional movement by the presence of said bracket. A pair of counter-balancing levers 25 is arranged with one near each side of frame 1 and extending longitudinally thereof substantially parallel to and spaced laterally from the lever 22, the forward ends of the levers 25 being connected by a cross bar 26 which underhangs and engages the forward end portion of lever 22 and stresses the same upward incident to the pressure of weights 27, 27, adjustably mounted on the rear end portions of the levers 25. A set screw 28 is provided for each weight 27 for adj ustably securing the weight to its respective lever 25. Each lever 25 is pivoted to and between a pair of brackets 29 fixed to and upstanding from the same plate of frame 1 from which the brackets 23 and 24 upstand.

The bracket 19 is of a width considerably greater than the width of cam 18, and at each side of the cam within the bracket 19 is arranged a lever 30, the two levers 30 being pivoted on the same pin carried by bracket 19 on which cam 18 is pivoted. The two levers 30 are employed as asingle lever and are duplicated to provide an effective balancing of the parts. tions of the levers 30 are connected by a cross bar 31 in which is anchored the upper end portion of a plunger rod 32 surrounded by a coiled actuating spring 33. The coiled spring 33 surrounds the rod 32 and is tensioned between the cross bar 31 at one end and the plate of frame 1 from which the several brackets 23, 24 and 29 upstand. A pair of posts or bars 34 is arranged between the last-named plate and the plate 21, and the bars 34 are fixed to both so as to lie just outside of the two levers 30 and to serve as guides therefor to prevent any torsional or other undesired movements of levers 30. A latch or trigger bar is pivoted to a bracket 36 upstanding from the same plate of frame 1 as that carrying the brackets 23 and 24.; and a post 37 is fixed to and upstands from said plate in position for sustaining the longer end portion of bar after a trip operation and up to the time of the re-setting action. The bar is of a length snflicient to extend just beneath the rear end of lever 22 when the forward end of said lever is in its raised position. As the bar 35 thus laps beneath the lever 22, when the parts are in the position indicated in, Figure 5, the lever 22 retains the bar 35 in such position against the upward pressure of the cross bar 31, of levers 30. It will be observed that the weights 27 are proportioned and adjusted to retain the levers 25 in position for sustaining the lever 22 in its raised position against the stress of spring 32 on the bar 35.

After as trip a mechanism; "has thus been actuah id it" is necessary to rev-set the same for tlie" is being re-set. A--cable "re engages tlie 'iior- Waa'ch end-1 of lever-22 and extends downward through a portion of frame 1 about a shive 43 carried by the frame andfto theinner end of rod 39 to whichthecable hiiis fixed. A similar cable 44 is fixed to thecross bar 31 and extends down through a portion of frame 1 about a shive 45 carried by said frame and to the rod 40, and to the inner end of which the cable 41-4 is connected. After the rod 38 has been pressed in, the handles 41 of rods 39 and 40 are grasped and the rod 39 is pulled out or away from the frame so as to pull the lever 22 with the cross bar 26 and Weighted levers 25, down low enough to permit the assageof the longer end of bar 35; and hen, While therod 39 is held in its outer position, the rod 4-0 is pulled out for pulling down the cross bar 31Which moves from its upper posit-ion, not shown, to the position seen in Figure 4, and then as it moves further downward, toward the position seen in Figure 5, the short end of bar 35 is struck by the cross bar 31 and the bar 35 is thereby swung, after the manner indicated in dotted lines in Figure 4, until it assumes the position seen in Fig ure 5, the rear end of lever22 being meanwhile held in its raised position by the retention of the rod 39 in its outer position.

As soon as the bar 35 assumes the position indicated in Figure 5, rod 39 is released, and the weights 27 will lift the forward end of lever 22 and cause the rear end to overhang the forward end of bar 35; thus locking the bar 35 and the cross bar 31' under the force of the Weights 27 in the o sitionseen in Figure 5; The-frb'dtflis then released and the parts as-seieaey Ffor an- 'rherreperaaen.
